    <p>The below program should display subsets where elements are separated by '|'. Here i am using static String array allocation. But it doesn't show output for array size >19. It did not throw exception. How to resolve this?</p> <pre><code>class kkk { static int set[]={3,4,9,14,15,19,28,37,47,50,54,56,59,61,70,73,78,81,92,95,97,99}; static int arr_size=(int)Math.pow((double)2,(double)set.length); static String []abc=new String[arr_size+10]; static String wwf=""; static void subset(int x) { if(abc[0].equals("END")) { abc[0]=""+x; } else { int i,len=0,count=0; for(i=0;i&lt;abc.length;i++) { if(!abc[i].equals("END")){len=len+1;} } count=len; wwf=""; for(i=0;i&lt;len;i++) { wwf=abc[i]; wwf=wwf+"|"+x; abc[count]=wwf; count++; } abc[count]=""+x; } } static void sub() { int len=set.length,i; for(i=0;i&lt;len;i++) { subset(set[i]); } int count=0; for(i=0;i&lt;abc.length;i++) { System.out.println("count:"+count+++"-----"+abc[i]); } } public static void main(String args[]) { for(int i=0;i&lt;abc.length;i++) { abc[i]="END"; } sub(); } } </code></pre> <p>For ivanovic: Whats the output of the following program?</p> <pre><code>class kkk { static int valid_subset() { int count=0,len=abc.length,subset_count=0; for(int i=0;i&lt;len;i++) { if(!abc[i].equals("END")) { count=count+1; } } String www=""; for(int i=0;i&lt;count;i++) { int temp_large=0,sum=0,x=0; www=abc[i]; String fgr=""; for(int j=0;j&lt;www.length();j++) { if(!(""+www.charAt(j)).equals("|")) { fgr=fgr+www.charAt(j); x=Integer.parseInt(fgr); } else { if(x&gt;temp_large) { temp_large=x; } fgr=""; } } if(x&gt;temp_large) { temp_large=x; } fgr=""; for(int j=0;j&lt;www.length();j++) { if(!(""+www.charAt(j)).equals("|")) { fgr=fgr+www.charAt(j); x=Integer.parseInt(fgr); } else { if(x!=temp_large) { sum=sum+x; } fgr=""; } } if(x!=temp_large) { sum=sum+x; } if(temp_large==sum) { subset_count=subset_count+1; } } return subset_count; } static int set[]={3,4,9,14,15,19,28,37,47,50,54,56,59,61,70,73,78,81,92,95,97,99}; static int arr_size=(int)Math.pow((double)2,(double)set.length); static String []abc=new String[arr_size+10]; static String wwf=""; static void subset(int x) { if(abc[0].equals("END")) { abc[0]=""+x; } else { int i,len=0,count=0; for(i=0;i&lt;abc.length;i++) { if(!abc[i].equals("END")){len=len+1;} } count=len; wwf=""; for(i=0;i&lt;len;i++) { wwf=abc[i]; wwf=wwf+"|"+x; abc[count]=wwf; count++; } abc[count]=""+x; } } static void sub() { int len=set.length,i; for(i=0;i&lt;len;i++) { subset(set[i]); } /*int count=0; for(i=0;i&lt;abc.length;i++) { System.out.println("count:"+count+++"-----"+abc[i]); }*/ } public static void main(String args[]) { for(int i=0;i&lt;abc.length;i++) { abc[i]="END"; } sub(); System.out.println(valid_subset()); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
